No, it's not. LDW don't give estimates for a very good reason; things happen, real life gets in the way and this early on in development, there's no way of knowing for sure how long it'll take. Even trying to pin it down to a month is unrealistic.

I have to say that this is one of the things I do like about LDW; while I may not be a fan of every single one of their games and there are a couple I wouldn't recommend, the amount of time they take in developing and beta testing means I've never had any problem with bugs. I'd rather wait for a polished, perfect game than have them rush through just to satisfy demands
